GAS-BURNER TIP.

SPECIFICATION forming part of Letters Patent N o. 715,035, dated December 2, 1902.

Application filed January 14, 1902. Serial No. 89,671. (No model.)

To @ZZ whom, t 71u03/ concern:

Beit known that I, EDWARD DOWNEY, a citizen of the United States, residing in the city of New York, borough of Manhattan, and State of New York, have invented certain new and usefullmprovements in Gas-Burner Tips, of which the following is a specification.

This invention relates to a gas-burner tip that can be readily litted to an ordinary burner-tube and which is provided with a spreading-lip for increasing the efficiency of the gas-flame.

The object of the invention is to provide a metallic burner-tip that can be reliably fitted in the burner-tube with a spreading-lip that is secured in permanent relation with the aperture of the burner-tip. It has the advantage of obviating the necessity of adjusting the spreading-lip on the burner-tube, which adjusting is the objection to the gasburner attachments of this character, as it is necessary to observe care in adjusting the same in vertical and parallel position relative to the aperture of the burner-tip.

To obviate this necessity, the invention consists of a metallic gas-burner tip that has concavities on two opposite sides of its aperture, a spreading-lip secured to the burnertip at one side of the aperture and concavities, the spreading-lip having a semicylindrical depression at its lower edge and forwardlyprojecting lugs curved inwardly for clasping the burner-tip, as will be more fully described hereinafter and finally pointed out in the claim, reference being had to the accompanying drawings, in which- Figure l is a front view of the burner-tip provided with a spreading-lip. Figs. 2 and 3 are respectively side and top views of the same. Fig. 4t is a transverse section on lineV 4 4, Fig. 2; and Fig. 5 is a rear view of the` invention, showing the spreading-lip secured to the burner-tip by a single rivet.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, a represents a metallic burner-tip that is tapering toward its lower end, so as to be readily fitted in the gas-burner tube. The burner-tip is provided with the aperture of and with the concavities c2 adjacent the aperture d and on opposite sides of the same. Secured to the burner-tip a, arranged at one side of the orifice a', is the spreadinglip b, made preferably of sheet metal and which is provided with a semicylindrical depression b at its lower edge. The lugs b2, projecting forwardly, are curved inwardly from said semicylindrical depression b and serve as means for clasping the burnertip, but which are secured thereto by means of the rivets b3, passing through registering holes in the lugs and the burner-tip. By this construction of the spreading-lip having the clasping-lugs b2 the same can be secured firmly to the burner-tip by using a single rivet b4 by providing it in the center line 0f the depression b', as shown in Fig. 4, by reason of the lugs having the curvature of the burner-tip. The spreading-lip b is secured permanently to the burner-tip in proper relation to the aperture, so as to obviate the necessity of repeated trials to adj ust the same to the burner-tip, as was necessary in the attachments formerly used. By thus providing the burner-tip with the spreading-lip b a proper supply of air to be mixed with the gas is afforded before the gas reaches the zone of combustion of the flame, or otherwise the air supplied would be curtailed by the spreading-lip, completely excluding air froln the flame from one side. The gas issues from the aperture in a somewhat broad column adjacent the tip, and at this point air is drawn to the opposite broad sides of this column in upward direction over the concavities, so that the air concentrates at the aperture of the tip, as shown by the arrows in Fig. l, so as to be mixed thoroughly with the gas, whichas it ascends flares upwardly to form a fan-shaped flame parallel to the spreadinglip and possesses a superior quality of brightness.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination of a metallic burner-tip having concavities on opposite sides of its aperture, and a spreading-lip secured to said burner-tip adjacent said aperture and conmy invention I have signed my naine in prescavities and parallel With the center plane ence of two subscribing Witnesses. through said aperture and oonoavities, the r lower edge of said spreading-lip being dis- EDWARD DOWNEL 5 posed below said ooncavities, substantially Witnesses:
